100 Ounce Gold Bar Price in Canada — How the Live CAD Price Works
The 100 ounce bar is an institutional weight: one hundred troy ounces — over three kilos of gold — at the lowest premium per ounce in the minted range. It is bought by serious private investors and dealers, stored professionally, and sold back through dealers rather than over a retail counter. Gold Stock Corp publishes live Canadian-dollar gold prices across this site, and this page explains what a 100 ounce gold bar actually costs and what it sells for: the spot price in Canadian dollars, the premium a bar of this weight carries, and why the two numbers are never the same.
From the spot price to a bar price
The gold spot price is the world market price for one troy ounce (31.1035 grams) of refined gold, quoted in US dollars. Converted at the live USD/CAD exchange rate it gives the Canadian-dollar price per troy ounce — and a 100 ounce bar weighs 3,110.35 g, so its metal value is that per-ounce figure scaled by its weight in ounces. It moves whenever either the world price or the loonie moves. Every live price on this site is shown in Canadian dollars for exactly that reason: it is the currency you will actually transact in at a Canadian counter.
The premium on this weight
A real bar costs spot plus a premium covering minting, assay certification, packaging and distribution. That premium is a larger share of the price on small bars and a smaller share as weight rises — which is why the per-ounce cost of a 1 ounce bar is far above the per-ounce cost of a kilo bar, and why buyers comparing dealers should compare the total delivered price for the same weight and mint, not a headline spot figure. When you sell, a dealer buys back at a price built from the same live spot, less a margin that depends on the bar's form and condition; sealed, assay-certified bars from recognised mints — including AARUS bars minted in Canada — are the most liquid.
Tax and transacting in Canada
Investment-grade gold bars that meet the Royal Canadian Mint purity standard are a GST/HST-exempt supply in Canada, so no GST/HST is added to a qualifying 100 ounce bar. Gold Stock Corp buys and sells this weight at all three of its stores — our Mississauga head-office store (1323 Matheson Blvd E), our Malton store (7086 Airport Rd #3) and our Vancouver store (736 Granville St #510) — and by insured delivery and mail-in across Canada, always priced from the live feed at the moment of the transaction, with the breakdown explained before you commit.
Frequently asked questions
What is a 100 ounce gold bar worth today?
Its weight in troy ounces multiplied by the live Canadian-dollar spot price per ounce, plus a minting premium when you buy — the live ticker on this site shows the current spot price the calculation starts from.
Why does the per-ounce price fall as bars get bigger?
Minting, assay and packaging cost roughly the same per bar whatever its weight, so spreading them over more ounces lowers the cost per ounce. Larger bars are cheaper per ounce; smaller bars are more flexible to sell in pieces.
Is GST/HST charged on this bar?
No — qualifying investment-grade gold bars are a GST/HST-exempt supply in Canada.
Where can I buy or sell a 100 ounce bar?
At Gold Stock Corp's Mississauga, Malton and Vancouver stores in person, or anywhere in Canada by insured delivery for purchases and insured mail-in for sales.
